“…A lowering of the larynx will decrease the relation of the epilaryngeal tube to the pharynx cross section and will therefore also contribute to a clustering of resonances 3–5 [ 36 ]. The contrast of the presented data to Neuschäfer-Rube et al [ 46 ] might be related to the fact that not all singers use formant/resonance clustering or that they accept timbre changes associated with an elongation of the vocal tract.…”

“…Lastly, while a vertical rise of the larynx was correlated with a rising pitch, the larynx was found at a lower vertical position in the louder dynamical conditions. This finding is in agreement with Luchsinger and Arnold [ 40 ] and Shipp [ 41 ] but in contrast to Neuschäfer-Rube et al [ 46 ]. An elongation of the vocal tract will lower the vocal tract resonance frequencies.…”

“…Due to the increased noise exposure there is very little articulatory data of the vocal tract achieved by MRI which reflects different loudness or sound pressure conditions. In their early MRI studies, Neuschäfer-Rube et al [ 46 ] were not able to observe great differences concerning the vertical laryngeal position in relation to different loudness conditions. However, the same research group found changes in the oro-pharyngeal part of the vocal tract [ 47 ].…”

IntroductionDynamic MRI analysis of phonation has gathered interest in voice and speech physiology. However, there are limited data addressing the extent to which articulation is dependent on loudness.Material and Methods12 professional singer subjects of different voice classifications were analysed concerning the vocal tract profiles recorded with dynamic real-time MRI with 25fps in different pitch and loudness conditions. The subjects were asked to sing ascending scales on the vowel /a/ in three loudness conditions (comfortable = mf, very soft = pp, very loud = ff, respectively). Furthermore, fundamental frequency and sound pressure level were analysed from the simultaneously recorded optical audio signal after noise cancellation.ResultsThe data show articulatory differences with respect to changes of both pitch and loudness. Here, lip opening and pharynx width were increased. While the vertical larynx position was rising with pitch it was lower for greater loudness. Especially, the lip opening and pharynx width were more strongly correlated with the sound pressure level than with pitch.ConclusionFor the vowel /a/ loudness has an effect on articulation during singing which should be considered when articulatory vocal tract data are interpreted.

It is well known that alterations to the oral cavity caused by dental prostheses may affect speech articulation, although influences on the voice are not assumed. In addition to the vocal fundamental frequency, vibrations of the vocal chords generate overtones. Through the shape of the larynx and the upper airway, resonances and antiresonances are formed, and in this way overtones are amplified to a variable extent. Nozzle changes caused by a dental prosthesis in the oral cavity may possibly influence overtones but influences on the vocal fundamental frequency seem unlikely. The influence of dental prostheses on the voice is demonstrated in a patient who owned two different dental prostheses. The fundamental frequency rose by up to five semitones during speech and his vocal range increased by up to four semitones when a thin denture was used instead of a normal denture. When the position of the mandible was checked by intraoral needle point placement, a more rostral position of the mandible was recorded with the thin denture than with the normal denture. Sagittal magnetic resonance tomography imaging also showed that the larynx was in a more cranial position. This change was presumed to be due to an upward movement of the larynx induced by the tongue, which itself was found to be in a more cranial position with the thin denture. In this situation, increased tension of the laryngeal muscles were believed to induce a rise in fundamental frequency, shifting the voice range toward higher frequencies. These findings show that dental prostheses can cause vocal changes in individual cases. The etiology of this occurrence is still not clear. Its consequences, however, should be known to the dentist, ENT surgeon and phoniatrist if patients notice changes in their voice after having altered or replaced their dentures.
